Abstract
The utility model discloses a kind of hoop energy collecting type powder column housing, comprise the lid that binds, powder column body, sealing bottom three major parts, be mainly used in Cut Blasting aspect, the utility model is arranging hoop hemispherical groove on cylindrical grain, powder column explosion time, on powder column, the rock at hoop hemispherical groove place is under the effect of cumulative detonation metal flow, the fissure-plane along powder column radial direction is formed in hemispherical groove region, do not do the powder column part explosion time of hemispherical groove process, the length of rock crackle forming can be increased further, under follow-up big gun hole detonation, by rock crushing within the scope of vallecular cavity, and throwing goes out vallecular cavity, this can improve Cut Blasting effect, and the utility model and equal length are compared with traditional powder column of diameter and are more saved explosive.
Description
Technical field
The utility model relates to a kind of powder column housing, particularly relates to a kind of hoop energy collecting type powder column housing.
Background technology
Unfavorable factor in Cut Blasting has 2: one to be that the scope of freedom is single, and rock is volumetric expansion in shattering process, and single degree of freedom face cannot provide sufficient expansion space to be the main cause causing slotting effect poor; Two is clamping actions of rock mass, and along with mining depth increases, the clamping action in Cut Blasting between rock block significantly increases, and this is another unfavorable factor of Cut Blasting.At present, a series of research work has been carried out in order to realize stone head speedy drivage, this improves cyclic advance to a certain extent, but to the unfavorable factor how overcome in Cut Blasting, the research improving blast hole utilizing factor is still not deep enough, in explosion powder column, just need badly and develop a kind of saving explosive, the powder column that slotting is effective.
Summary of the invention
In order to overcome the unfavorable factors such as the single and rock clamping action in the scope of freedom in current Cut Blasting, the utility model provides a kind of hoop energy collecting type powder column housing.
The utility model solves the technical scheme that its technical problem adopts:
A kind of hoop energy collecting type powder column housing, comprises top pressure closure (1), powder column body (2), sealing bottom (3) three major parts, below said " up and down " refer to the position relationship in Figure of description;
Described top pressure closure (1) is concave plastic closure, inner lid has two circumferential groove, outer wall has two hoop projections, and bottom is hemispherical, directly covers on powder column body (2) top;
Described powder column body (2) is the cylindrical cavity body of rod, for PVC material, the body of rod is distributed with hoop hemispherical groove (4), both the body of rod diameter containing hoop hemispherical groove is less than not containing the diameter of groove, its upper inside wall there are two circumferential groove, lower inner wall is internal thread, has two circular ports (5) diametrically in powder column body (2) bottom;
Hoop hemispherical metal energy gathering cap (6) housing is provided with in described hoop hemispherical groove (4);
Described sealing bottom (3), outer wall has two hoop projections, and bottom is hemispherical, and sealing bottom (3) top is external screw thread, and sealing bottom (3) is connected by screw thread with between powder column body (2);
Operation principle:
The utility model arranges hoop hemispherical groove on traditional cylindrical powder column, according to the principle of jet perforating, powder column explosion time, when detonation wave arrives metal cumulative cover, metal cap is owing to being subject to strong compression, inner surface portion metal is out squeezed, along hemispherical groove outside jet at a high speed, energy is also the most concentrated, there is stronger directed width generation capacity, the fissure-plane along powder column radial direction is formed in hemispherical groove region, do not do the powder column part explosion time of hemispherical groove process, the length of rock crackle forming can be increased further, under follow-up big gun hole detonation, by rock crushing within the scope of vallecular cavity, and throwing goes out vallecular cavity.
Compared with prior art, the utility model has the advantages that:
The utility model arranges hoop hemispherical groove on cylindrical grain, and this compares with equal length can save explosive with the powder column of diameter, also can significantly improve the rock breaking capacity of powder column; The utility model is according to the explosion thought of " first cut and draw afterwards ", powder column explosion time, on powder column, the rock at hoop hemispherical groove place produces many crackles under the effect of cumulative detonation metal flow, and the fissure-plane formed in hemispherical groove region along powder column radial direction, powder column there is no the part explosion time of hoop hemispherical groove, detonation wave can strengthen the fragmentation of keyhole surrounding rock, then under follow-up big gun hole detonation, by rock crushing within the scope of vallecular cavity, and throwing goes out vallecular cavity, this can improve Cut Blasting effect, and improves cyclic advance to a certain extent.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
A kind of hoop energy collecting type powder column housing, comprises top pressure closure (1), powder column body (2), sealing bottom (3) three major parts, below said " up and down " refer to the position relationship in Figure of description;
Described top pressure closure (1) is concave plastic closure, inner lid has two circumferential groove, outer wall has two hoop projections, and bottom is hemispherical, directly covers on powder column body (2) top;
Described powder column body (2) is the cylindrical cavity body of rod, for PVC material, the body of rod is distributed with hoop hemispherical groove (4), both the body of rod diameter containing hoop hemispherical groove is less than not containing the diameter of groove, its upper inside wall there are two circumferential groove, lower inner wall is internal thread, has two circular ports (5) diametrically in powder column body (2) bottom;
Hoop hemispherical metal energy gathering cap (6) housing is provided with in described hoop hemispherical groove (4);
Described sealing bottom (3), outer wall has two hoop projections, and bottom is hemispherical, and sealing bottom (3) top is external screw thread, and sealing bottom (3) is connected by screw thread with between powder column body (2).
By reference to the accompanying drawings the course of work of the present utility model is described:
As shown in Figure 1, sealing bottom (3) top is external screw thread, powder column body (2) lower inner wall is internal thread, after both are tightened, main charge and priming can be loaded successively inside powder column, then as required, if this powder column is not as big gun head, then top pressure closure (1) can directly be covered; If this powder column is as big gun head, then need the detonator inserting band payment to a porter in the priming of powder column top, and in the boring of top pressure closure (1) bottom portion of groove, be convenient to detonator payment to a porter and pass, after being placed by detonator, cover top pressure closure (1) again; Two hoop projections now on top pressure closure (1) outer wall enter in two circumferential groove in powder column body (2) upper inside wall, realize top pressure closure (1) and powder column body (2) connection between the two with this;
A kind of hoop energy collecting type powder column housing processing and fabricating of the present utility model is very simple and convenient, processing and fabricating shown in by specification accompanying drawing, when multiple powder column will be adopted to be connected, powder column can be joined end to end, two hoop projections of now powder column sealing bottom (3) outer wall enter in two circumferential groove of top pressure closure (1) inwall, easy to connect between two powder columns;
Pass two, powder column body (2) bottom circular port (5) diametrically successively with the steel wire of a some strength, can prevent powder column from dropping out, then the utility model can use in the keyhole tilted upward.
